Power electronic arrangement device with cooling arrangement

Abstract

The invention discloses a power electronic arrangement device with cooling arrangement, which comprises a mounting plate, a cooling box is fixedly mounted at the top of the mounting plate, a mounting groove is formed in the mounting plate, first absorbent cotton is fixedly mounted at the bottom of the mounting groove, and a breathable leakage net is fixedly mounted at the top of the first absorbent cotton. A heat conduction column is fixedly installed at the top of the ventilation leakage net, second absorbent cotton is fixedly installed at the top of the inner side of the cooling box, a partition plate is fixedly installed at the bottom of the cooling box, a first cooling fan is fixedly installed at the top of the partition plate, and a fixing frame is fixedly installed between the second absorbent cotton and the partition plate in the cooling box; a plurality of heat dissipation fins are fixedly installed in the fixing frame, and cooling pipes are arranged among the heat dissipation fins in a penetrating mode. The power electronic arrangement device with the cooling arrangement is simple and reasonable in structure and convenient to use, effectively solves the problems that cooling devices of most existing power electronic arrangement devices are low in cooling efficiency, lack of dustproof devices and single in function, and has high practical value.

Description

technical field [0001] The invention relates to the technical field of cooling devices, in particular to a power electronic arrangement device with a cooling arrangement. Background technique [0002] Power electronic devices are devices composed of various power electronic circuits. It is used for the conversion and control of high-power electric energy. Also known as a flow converter. It includes rectifiers, inverters, DC converters, AC converters, various power supplies and switches, motor speed control devices, DC transmission devices, induction heating devices, reactive power compensation devices, electroplating electrolysis devices, household appliances inverters device etc. [0003] Among them, the DC power supply can be composed of a rectifier or a DC converter, which is used for DC motor speed regulation, charging (recharging power supply), electroplating and scientific instruments. The AC power supply can be composed of a frequency converter. Divided into vari...

Problems solved by technology

[0004] The cooling devices of most existing power electronic layout devices still have the following deficiencies: 1. The cooling method is single, usually only water cooling or air cooling is used, and the cooling efficiency is low; 2. The lack of dust-proof devices is easy to accumulate dust, which is not conducive to heat dissipation in the cold area ; 3. The lack of humidity detection device is not conducive to the adjustment according to the humidity, and the function is single; therefore, we make an improvement on this and propose a power electronic arrangement device with a cooling arrangement
